Green tea extract is valued for its antioxidant, anti-inflammatory, and antimicrobial properties. It contains polyphenols, particularly epigallocatechin gallate (EGCG), which help protect the skin from oxidative stress caused by free radicals, environmental pollutants, and UV radiation. These antioxidants can help prevent premature aging, reduce the appearance of fine lines and wrinkles, and promote a more youthful complexion.
